The late Sir Nicholas Winton saved the lives of 669 children, most of them Jewish, when he organised for them to leave Czechoslovakia for his native UK on the eve of WWII. His daughter Barbara Winton has told his remarkable story in the book If It's Not Impossible...: The Life of Sir Nicholas Winton.
